Back on the Fantasti-Sub, Sue sat on her sissy brother's lap, rocking her hips back and forth, grinding her wet snatch on his little prick. She tugged his head back by the longer hair she'd had him grow, planting hot kisses on his bare neck. With her other
hand she pinched and teased his nipples, the little squeaks and gasps he gave off were delicious. Sue really did love the role of dominatrix to her little brother.
Across the room, The Thing snorted through his new snout, tugging and shaking against the invisible restraints Mistress Susie had him under. His enormous cock was bolt upright, twitching and jerking around on its own, pre-cum seemed to sputter out of the
pointed tip endlessly.
"Looks like I'm driving you a little crazy there Benjy" Sue grinned as she rocked back and forwards in front of the great beast. "Bet you'd love to shove that big hot rod into mistress's little honey pot wouldn't you?"
Ben was beyond words, the animal lusts of his new form seemed to override his higher brain functions.
"But I need you well revved up to go wild on Namorita, I want to see you totally ruin that little cunt."
The Sub's console ding-ed, indicating their final approach to Atlantis. "Oh, lucky you Ben, looks like we've arrived!" She observed the monster cock again, licking her lips. "Sorry baby brother, looks like we're going to have to finish. Johnny, cum!"
Johnny groaned as his voice triggered orgasm took over and he shot his load into Sue. With an air of half interest, Sue climbed off him mid spurt, and went over to the ship's controls as his sperm dripped out of her.
